    The Pristine Inner Galaxy Survey (PIGS) VII: a discovery of the first inner Galaxy CEMP-r/s star
    Well-studied very metal-poor (VMP, [Fe/H] <-2) stars in the inner Galaxy are few in number, and they are of special interest because they are expected to be...

    The Pristine Inner Galaxy Survey (PIGS): IX. The largest detailed chemical analysis of very metal-poor stars in the Sagittarius dwarf galaxy
    The most metal-poor stars provide valuable insights into the early chemical enrichment history of a system, carrying the chemical imprints of the first...

    The Pristine survey - I. Mining the Galaxy for the most metal-poor stars
    We present the Pristine survey, a new narrow-band photometric survey focused on the metallicity-sensitive Ca H&K lines and conducted in the Northern hemisphere...

    The Pristine survey - VII. A cleaner view of the Galactic outer halo using blue horizontal branch stars
    We use the Pristine survey CaHK narrow-band photometry, combined with the Sloan Digital Sky Survey (SDSS)ugr photometry, to provide a cleaner sample of blue...

    The Pristine Survey - VIII. The metallicity distribution function of the Milky Way halo down to the extremely metal-poor regime
    The Pristine survey uses narrow-band photometry to derive precise metallicities down to the extremely metal-poor regime ( [Fe/H] < -3), and currently consists...

    The Pristine survey - XV. A CFHT ESPaDOnS view on the Milky Way halo and disc populations
    We present a one-dimensional, local thermodynamic equilibrium homogeneous analysis of 132 stars observed at high resolution with ESPaDOnS. This represents the...

    The Pristine survey - XVIII. C-19: tidal debris of a dark matter-dominated globular cluster?
    The recently discovered C-19 stellar stream is a collection of kinematically associated metal-poor stars in the halo of the Milky Way lacking an obvious...

    The Proper Motion Field of the Small Magellanic Cloud: Kinematic Evidence for Its Tidal Disruption
    We present a new measurement of the systemic proper motion of the Small Magellanic Cloud (SMC), based on an expanded set of 30 fields containing background...

    The Proper-motion Field along the Magellanic Bridge: A New Probe of the LMC–SMC Interaction
    We present the first detailed kinematic analysis of the proper motions (PMs) of stars in the Magellanic Bridge, from both the Gaia Data Release 2 catalog and...
